Hello, I have a trio of sub-adult crested geckos in a tank aprox. 16in x 17in x 48in. This is a screen top aquarium placed on its side.



My understanding is that crested geckos do best in around 70% humidity. I am having great difficulty raising humidity to even 50%!



The substrate is green moss (dried) over perlite. The screen top has plastic wrap over all of the top half (except 2 aprox 1in x 1in spots) and over all but the lowest 1.5 inches at the bottom. Live plants are on the bottom. I used to mist the tank heavily at least 2 times daily but now have installed Zoo Med's Habba Mist system. It is set to mist every hour for 30 seconds. I did have it set for longer, but water literally runs out the bottom of the cage, along the door.



Moss inside is not just damp, it is sopping wet. Yesterday I removed the moss and replaced it. Between a pail under the edge of the cage door and using paper towels to soak up standing water, there was probably close to a quart of water in there.



At a friends urging, I put a blanket over two sides and the top of the cage. The back of the cage is against a wall. Putting the blanket over the aquarium did raise the humidity 3%, which is how it got up as hgh as 49%.The weather here has been overcast and cloudy with light rain.



The crested geckos are showing some signs of low humidity, mainly being unable to scale the glass or to 'hold on' to it. They hold onto One in particular has toes noticably curling up whenever the humidity dips to 46%.



I am out of ideas for raising humidity. Please help!
